Efficacy and Safety of Coronary Sinus Aspiration During Coronary Angiography to Attenuate the Risk of Contrast-Induced Acute Kidney Injury in Predisposed Patients.

Background: The incidence of contrast-induced acute kidney injury is strongly related to the amount of the given contrast. Our objectives were to evaluate the efficacy and safety of coronary sinus aspiration (CSA) procedure to reduce the volume of the given contrast and attenuate the risk of contrast-induced acute kidney injury.

Methods And Results: The study included 43 patients with type 2 diabetes mellitus and renal impairment (creatinine 1.

Effect of experimental coronary sinus ligation on myocardial structure and function in the presence or absence of structural heart disease: an insight for the interventional electrophysiologist.

Aims: To study the effect of coronary sinus (CS) occlusion on normal hearts and hearts with structural disease.

Methods And Results: We included 32 dogs, divided into 4 groups: (1) CS ligation (CSL): subjected to CSL; (2) control group: no intervention; (3) MI-CSL group: subjected to myocardial infarction (MI) induction followed by CSL after 1 week; and (4) MI-control group: subjected to MI induction, then open thoracotomy after 1 week without CSL. Electrocardiography, echocardiography, histopathology, and immunohistochemistry were done before and after CSL.

Early Repolarization Pattern Is Associated with Increased Risk of Early Ventricular Arrhythmias during Acute ST Segment Elevation Myocardial Infarction.

Background: Early repolarization (ER) and acute ST segment elevation myocardial infarction (STEMI) are sharing the pathophysiology of J wave syndromes. It is speculated that early ventricular arrhythmias (VAs) during STEMI may be predisposed by ER. Our aim was to study the association between ER pattern and risk of VAs during acute STEMI.
